Sensitive tooth after semi-permanent filling. is this normal?

Maybe: If the filling is intact and strong enough, some sensitivity might be normal, but it should decrease over time. I suspect the reason for a "semi-permanent filling" is that the tooth might have a questionable prognosis. Please ask the dentist who placed the filling what he/she thinks about continued sensitivity.

Infection?: If still sensitive after a week, the tooth may be infected and surely dying = if so it will need either a root canal therapy or a tooth extraction. Check back with your dentist as an infection is nothing to play around with.
